Arduino OneButton Library This Arduino library is improving the usage of a singe button for input. It shows how to use an digital input pin with a single pushbutton attached for detecting some of the ...

Button-Controlled-LED-System-Using-Arduino This project demonstrates how to control 3 LEDs using 3 push buttons with an Arduino Uno. When a button is pressed, the corresponding LED lights up. This ...

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

Debouncing button or switch inputs on microcontrollers can be a challenging problem for those first starting to program these devices. Part of the reason for this difficulty is that real-world butt… ...

When the Arduino code sees the button getting pressed, it brings the corresponding LED pin high and starts a fade out timer using the SoftPWM library by [Brett Hagman].

Push button, ground out pin, input goes low. You do have inverted behavior (low is a pressed button), but that's not exactly hard to work with in software ...
